1.
Ivy's Whip-Sword from Soul Calibur - it'd be useful for aesthetic purposes if I decided to do cosplay, give me a chance to learn a crazy form of swordfighting, and to top it off, possibly inspire me to tweak it so that it can shapeshift into other weapons
2.
Hearthstone from World of Warcraft - Cut down on transportation whenever I go out, especially taking the train from my hometown to SF.
3.
The Maromi Plush Doll from Paranoia Agent - Creepiest little thing I've ever seen... >.>
I don't really care so much about powers (although they would be cool), but these would be the best novelty items I could have in the meanwhile. ^^
